产品描述： 140CPU53414B
日本的FANUC公司、立石公司、三菱公司、富士公司等所生产的PLC产品，都采用梯形图编程。在用编程器向PLC输入程序时，一般简易编程器都采用编码表输入，大型编程器也可用梯形图直接输入。在众多的PLC产品中，由于制造厂家不同，其指令系统的表示方法和语句表中的助记符也不尽相同，但原理是完全相同的。在本书中我们以FANUC-PMC-L为例，对适用于数控机床控制的PLC指令作一介绍。在FANUC系列的PLC中，规格型号不同时，只是功能指令的数目有所不同，如北京机床研究所与FANUC公司合作开发的FANUC-BESK PLC-B功能指令23条，除此以外，指令系统是完全一样的。
在FANUC-PMC-L中有两种指令：基本指令和功能指令。当设计顺序程序时，使用最多的是基本指令，基本指令共12条。功能指令便于机床特殊运行控制的编程，功能指令有35条。
在基本指令和功能指令执行中，用一个堆栈寄存器暂存逻辑操作的中间结果，堆栈寄存器有9位（如图1所示），按先进后出、后进先出的原理工作。当前操作结果压入时，堆栈各原状态全部左移一位；相反地取出操作结果时堆栈全部右移一位，最后压入的信号首先恢复读出。
